Climate Conditions

In the Arctic part of the Nordic region, cultivated crops need to specifically adapt to adverse and extreme climate conditions, such as low temperatures, long days, and a short growing season. Under the projected climate change scenarios, higher temperatures and an earlier spring thaw will gradually allow the cultivation of plants that could not be previously cultivated there. For millennia, Pea (Pisum sativum L.) has been a major cultivated protein plant in Nordic countries but is currently limited to the southern parts of the region. However, response and adaptation to the Arctic day length/light spectrum and temperatures are essential for the productivity of the pea germplasm and need to be better understood. This study investigated these factors and identified suitable pea genetic resources for future cultivation and breeding in the Arctic region. Fifty gene bank accessions of peas with a Nordic landrace or cultivar origin were evaluated in 2-year field trials at four Nordic locations in Denmark, Finland, Sweden, and Norway (55° to 69° N). The contrasting environmental conditions of the trial sites revealed differences in expression of phenological, morphological, crop productivity, and quality traits in the accessions. The data showed that light conditions related to a very long photoperiod partly compensated for the lack of accumulated temperature in the far north. A critical factor for cultivation in the Arctic is the use of cultivars with rapid flowering and maturation times combined with early sowing. At the most extreme site (69°N), no accession reached full maturation. Nonetheless several accessions, predominantly landraces of a northern origin, reached a green harvest state. All the cultivars reached full maturation at the sub-Arctic latitude in northern Sweden (63°N) when plants were established early in the season. Seed yield correlated positively with seed number and aboveground biomass, but negatively with flowering time. A high yield potential and protein concentration of dry seed were found in many garden types of pea, confirming their breeding potential for yield. Overall, the results indicated that pea genetic resources are available for breeding or immediate cultivation, thus aiding in the northward expansion of pea cultivation. Predicted climate changes would support this expansion.

The yield potential, quality and level of resistance to powdery mildew (Erysiphe pisi DC.) of afila smooth seeded pea (Pisum sativum L.) were tested in the field trials. The cultivars and breeding lines Mozart, Consort-R, AGT-01, Cebeco 1171 and AGT-GH surpassed the control cv. Gotik in the yields of dry seed, in contrast the dry seed yields of Highlight, AGT-KR, Melfort and LU 390-R2 were about 12–27% lower than that of the control. The low seed yield was caused by virus infections (PEMV, BYMV), root diseases (Pythium, Fusarium), and a low level of thousand seeds weight (TSW). Material crossing with donors possessing high yield potential, a higher TSW, and a higher tolerance to root diseases had a positive effect on the dry seed yield. The main objective of the resistant pea breeding programme is afila smooth seeded pea resistant to powdery mildew, with a high tolerance to viruses, root diseases, and lodging, with the stem length of 60 to75 cm, and with high yield potential.

Aim. To assess the melon collection material for seed productivity and to identify sources of a valuable trait for involvement in the breeding process in the northern Steppe of Ukraine. Results and Discussion. Our analysis revealed relationships between the main economic traits, and we established that the productivity of fruits and seeds significantly depended on environmental factors during the study years. There was a strong correlation between these traits (r = 0.71), while the seed productivity more depended on the fruit number per plant (r = 0.62) than on their average weight (r = 0.41). The accessions under investigation differed by fulfillment of their seed yield potential. Among the accessions included in group 4 with high seed productivity, high seed yields were provided by such accessions as Desertnaia 5 (RUS), Ineia (UKR), Delicious 51 (USA), Chaika (UKR), Fortuna (UKR), and Pamiati Pangalo (MDA) (22.3-25.3 g/plant; 0.23-0.26 t/ha). Four accessions from group 5 were identified as the most valuable genetic sources of very high seed productivity: Mistseva 256/98 (UKR), Berehynia (UKR), Victoria (MDA), and Iliyskaya (KAZ) (26.8-29.6 g/plant; 0.27-0.30 t/ha), which exceeded the check variety by 12.8-5.6 g/plant or by 0.13-0.16 t/ha. The seed yield, as a measure of the potential number of seeds depending on the fruit yield, and the 1000-seed weight, as an indicator of the seed size and plumpness, are also important traits in assessing the seed productivity of collection accessions. The highest percentages of seed yield were observed in accessions Pepen golden (ROU), Ananasna 217/06 (RUS), Accession 4596 (USA), Mistseva 256/98 (UKR), Inhulka (UKR), Mistsevyi 5827 (KAZ), and Basarabiya (MDA): 1.23-1.42% (0.33-0.52% higher than from the check variety). As to the 1000-seed weight, the highest values were recorded for accessions Pridnestrovskaya (MDA), Lyleia (UKR), Dumka (UKR), Ineia (UKR), Mistseva 256/98 (UKR), Pamyati Pangalo (MDA), and Berehynia (UKR): 40.4-46.2 g (+3.9-9.7 g to the check variety). Due to the combination of high yield capacity and increased seed productivity, variety Berehynia (UL3800002) originating from Ukraine has been submitted for registration to the National Centre for Plant Genetic Resources of Ukraine as an accession of the gene pool. Conclusions. Assessment of the genetic diversity of melons revealed patterns in levels of seed productivity, depending on the variety; and the relationships between the main economic traits were determined. Sources of valuable economic traits for further use in breeding have been identified: with high seed productivity (10), with increased seed yield (7) and with large seeds (7). Valuable specimen of melon, Berehynia (UL3800002), with high seed productivity has been singled out and submitted for registration to the National Center for Plant Genetic Resources of Ukraine.

Flowering Regulation

AbstractHybrid japonica cultivars, such as the Yongyou series, have shown high yield potential in the field in both the early and late growing seasons. Moreover, understanding the responses of rice flowering dates to temperature and light is critical for improving yield performance. However, few studies have analyzed flowering genes in high-yielding japonica cultivars. Based on the five sowing date experiments from 2019 to 2020, select the sensitive cultivar Yongyou 538 and the insensitive cultivar Ninggeng 4 and take their flag leaves and panicles for transcriptome analysis. The results showed that compared with sowing date 1 (6/16), after the sowing date was postponed (sowing date 5, 7/9), 4480 and 890 differentially expressed genes (DEGs) were detected in the leaves and panicles in Ninggeng 4, 9275 and 2475 DEGs were detected in the leaves and panicles in Yongyou 538, respectively. KEGG pathway analysis showed that both Ninggeng 4 and Yongyou 538 regulated rice flowering through the plant circadian rhythm and plant hormone signal transduction pathways. Gene expression analysis showed that Os01g0566050 (OsELF3-2), Os01g0182600 (OsGI), Os11g0547000 (OsFKF1), Os06g0275000 (Hd1), and Os09g0513500 (FT-1) were expressed higher and Os02g0771100 (COP1-1) was expressed lower in Yongyou 538 compared with Ninggeng 4 as the climate conditions changed, which may be the key genes that regulate the flowering process with the change of temperature and light resources in sensitive cultivar Yongyou 538 in the late season.
